Baccha elongata is a species of hoverfly (or flower fly) in the genus Baccha. Baccha elongata is present in most of Europe and in North America. Common and widely distributed throughout Britain and Ireland wherever there is suitable habitat though easily overlooked due to its unobtrusive nature. These hoverflies inhabit coniferous and deciduous forests, woodland, hedgerows, scrub and gardens Generally they prefer shady places low to the ground.
Baccha elongata can reach a length of 7–11 millimetres (0.28–0.43 in). It is one of the smaller hoverflies, the wing length is around 4.5 to 8 mm. The long, very slender body of these hoverflies is unmistakable. They also differ from other hoverflies by their elongated, thin abdomen ending in club. This club-shaped abdomen is black with a yellow spot on the 3rd and 4th segments. Legs are brownish yellow. Forehead is brightly hairy.
Members of the eristaline genus Sphegina are also very slender and can be found in similar habitat but those flies have a rather different enlarged hind femur, whereas in Baccha this feature is slender. As with most hoverfly species the sexes can be told apart by the... Wikipedia →

Rare
Under 5% of wildlife watchers report a Common Dainty sighting in Bavarian Forest National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 964th most-seen of the 1115 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
April and August
In those months about 10% of wildlife watchers report a Common Dainty in Bavarian Forest National Park on a given day, against under 5% in May–July and September–March, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Common Dainty sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Bavarian Forest National Park, in our data
Bavarian Forest National Park is the only park on Wallace's Line with enough records to rate Common Dainty sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Syrphidae
The closest relatives of the Common Dainty that you can see in Bavarian Forest National Park (family Syrphidae, Hover Flies) are Common Drone Fly (about 20%), Marmalade Hover Fly (about 20%) and Yellow-Haired Sun Fly (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Dainty is recorded against all the insects logged in Bavarian Forest National Park (5 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
